Description

Technical Field

[0001] The utility model relates to the field of sealing devices, in particular to a hydrogen-oxygen vacuum melting sealing device. Background Art

[0002] Oxyhydrogen vacuum sealing is a process for sealing glass tubes and other glass products using an oxyhydrogen flame. This technique is commonly used in laboratories to preserve samples in an oxygen- and water-free vacuum seal. The oxyhydrogen flame sealing machine electrolyzes water to produce hydrogen and oxygen. The hydrogen acts as fuel, while the oxygen assists combustion. Ignition produces an oxyhydrogen flame, which has a high temperature and emits no carbon, making it ideal for sealing operations requiring high purity and a clean environment.
